GENERAL

The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.

The refrigerant system is completely assembled and
charged. All internal wiring is complete.

The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.

These instructions explain the recommended method to
install the air cooled self-contained unit and the
electrical wiring connections to the unit.

recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made. See Page 3 for information on codes and
standards.

Size of unit for a proposed installation should be based
on heat loss calculation made according to methods of
Air Conditioning Contractors of America (ACCA). The
air duct should be installed in accordance with the
Standards of the National Fire Protection Association
for the Installation of Air Conditioning and Ventilating
Systems of Other Than Residence Type, NFPA No.
90A, and Residence Type Warm Air Heating and Air
Conditioning Systems, NFPA No. 90B. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.

Manual 2100-508F
Page 4 of 25

DUCT WORK

All duct work, supply and return, must be properly sized
for the design airflow requirement of the equipment. Air
Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing. All duct work or portions
thereof not in the conditioned space should be properly
insulated in order to both conserve energy and prevent
condensation or moisture damage.

Refer to Maximum ESP of operation Electric Heat Table 6.

FILTERS

A 1-inch throwaway filter is standard with each unit.
The filter slides into position making it easy to service.
This filter can be serviced from the outside by removing
the filter access panel. A 1-inch washable filter and 2­inch pleated filter are also available as optional
accessories. The internal filter brackets are adjustable
to accommodate the 2-inch filter by bending two (2)
tabs down on each side of the filter support bracket.

Design the duct work according to methods given by the Air
Conditioning Contractors of America (ACCA). When duct
runs through unheated spaces, it should be insulated with a
minimum of one inch of insulation. Use insulation with a
vapor barrier on the outside of the insulation. Flexible joints
should be used to connect the duct work to the equipment in
order to keep the noise transmission to a minimum.

Models W17 - W24 as approved for zero inch clearance to
the supply duct. For model series W30, W36, W42, W48,
W60 and W70 a 1/4 inch clearance to combustible material
for the first three feet of duct attached to the outlet air frame
is required. See Wall Mounting Instructions and Figures 3
and 4 for further details.

Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the wall
cavity.

Some installations may not require any return air duct. A
metallic return air grille is required with installations not
requiring a return air duct. The spacing between louvers on
the grille shall not be larger than 5/8 inch.

Any grille that meets with 5/8 inch louver criteria may be
used. It is recommended that Bard Return Air Grille Kit
RG2 through RG5 or RFG2 through RFG5 be installed
when no return duct is used. Contact distributor or factory
for ordering information. If using a return air filter grille,
filters must be of sufficient size to allow a maximum
velocity of 400 fpm.

FRESH AIR INTAKE

All units are built with fresh air inlet slots punched in
the service door.

If the unit is equipped with a fresh air damper assembly,
the assembly is shipped already attached to the unit.
The damper blade is locked in the closed position. To
allow the damper to operate, the maximum and
minimum blade position stops must be installed. See
Figure 1.

All capacity, efficiency and cost of operation
information is based upon the fresh air blank-off plate in
place and is recommended for maximum energy
efficiency.

The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.

CONDENSATE DRAIN

A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.

NOTE: If no return air duct is used, applicable installation

codes may limit this cabinet to installation only in a
single story structure.

INSTALLATION INSTRUCTIONS

WALL MOUNTING INFORMATION

1. Two holes for the supply and return air openings
must be cut through the wall as shown in Figure 3.

2. On wood frame walls, the wall construction must be
strong and rigid enough to carry the weight of the
unit without transmitting any unit vibration.

3. Concrete block walls must be thoroughly inspected
to insure that they are capable of carrying the weight
of the installed unit.

MOUNTING THE UNIT

1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket, attached to
skid for shipping, is provided for ease of installation,
but is not required.

2. The unit itself is suitable for 0 inch clearance, but
the supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1/4 inch
clearance to combustible material for model series
W30, W36, W42, W48, W60 and W70. However, it
is generally recommended that a 1-inch clearance is
used for ease of installation and maintaining the
required clearance to combustible material. See
Figure 3 for details on opening sizes.

3. Locate and mark lag bolt locations and bottom
mounting bracket location. See Figure 3.

WARNING

Failure to provide the 1/4 inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
fire causing damage, injury or death.

6. Position unit in opening and secure with 5/16 lag
bolts; use 7/8 inch diameter flat washers on the lag
bolts.

7. Secure rain flashing to wall and caulk across entire
length of top. See Figure 3.

8. For additional mounting rigidity, the return air and
supply air frames or collars can be drilled and
screwed or welded to the structural wall itself
(depending upon wall construction). Be sure to
observe required clearance if combustible wall.

9. On side-by-side installations, maintain a minimum
of 20 inches clearance on right side to allow access
to control panel and heat strips, and to allow proper
airflow to the outdoor coil. Additional clearance
may be required to meet local or national codes.

4. Mount bottom mounting bracket.

5. Hook top rain flashing, attached to front - right of
supply flange for shipping, under back bend of top.

WIRING – MAIN POWER

Refer to the unit rating plate for wire sizing information
and maximum fuse or “HACR” type circuit breaker
size. Each outdoor unit is marked with a “Minimum
Circuit Ampacity”. This means that the field wiring
used must be sized to carry that amount of current.
Depending on the installed KW of electric heat, there
may be two field power circuits required. If this is the
case, the unit serial plate will so indicate. All models
are suitable only for connection with copper wire. Each
unit and/or wiring diagram will be marked “Use Copper
Conductors Only”. These instructions must be adhered
to. Refer to the National Electrical Code (NEC) for
complete current carrying capacity data on the various
insulation grades of wiring material. All wiring must
conform to NEC and all local codes.

The electrical data lists fuse and wire sizes (75° C
copper) for all models including the most commonly
used heater sizes. Also shown are the number of field
power circuits required for the various models with
heaters.

The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or “HACR” type circuit breaker that is to
be used with the equipment. The correct size must be
used for proper circuit protection and also to assure that
there will be no nuisance tripping due to the momentary
high starting current of the compressor motor.

WIRING – LOW VOLTAGE WIRING

230/208V, 1 phase and 3 phase equipment dual primary
voltage transformers. All equipment leaves the factory
wired on 240V tap. For 208V operation, reconnect from
240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:

TAP RANGE

240 253 – 216
208 220 – 187

NOTE: The voltage should be measured at the field power

connection point in the unit and while the unit is
operating at full load (maximum amperage
operating condition).

For wiring size and connections, refer to Wiring Manual
2100-507.

The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect. To
convert for the locking capability, bend the tab located
in the bottom left-hand corner of the disconnect opening
under the disconnect access panel straight out. This tab
will now line up with the slot in the door. When shut, a
padlock may be placed through the hole in the tab
preventing entry.

See “Start Up” section for important information on
three phase scroll compressor start ups.

See Tables 3 & 4 for Electrical Specifications.

START UP

THESE UNITS REQUIRE R-410A
REFRIGERANT AND POLYOL
ESTER OIL.

GENERAL:

1. Use separate service equipment to avoid cross
contamination of oil and refrigerants.

2. Use recovery equipment rated for R-410A
refrigerant.

3. Use manifold gauges rated for R-410A (800 psi/250
psi low).

4. R-410A is a binary blend of HFC-32 and HFC-125.

5. R-410A is nearly azeotropic - similar to R-22 and
R-12. Although nearly azeotropic, charge with
liquid refrigerant.

6. R-410A operates at 40-70% higher pressure than
R-22, and systems designed for R-22 cannot
withstand this higher pressure.

7. R-410A has an ozone depletion potential of zero,
but must be reclaimed due to its global warming
potential.

8. R-410A compressors use polyolester oil.

9. Polyol Ester oil is hygroscopic; it will rapidly absorb
moisture and strongly hold this moisture in the oil.

10. A liquid line dryer must be used - even a deep
vacuum will not separate moisture from the oil.

11. Limit atmospheric exposure to 15 minutes.

12. If compressor removal is necessary, always plug
compressor immediately after removal. Purge with
small amount of nitrogen when inserting plugs.

TOPPING OFF SYSTEM CHARGE

If a leak has occurred in the system, Bard Manufacturing
recommends reclaiming, evacuating (see criteria above),
and charging to the nameplate charge. If done correctly,
topping off the system charge can be done without
problems.

With R-410A, there are no significant changes in the
refrigerant composition during multiple leaks and
recharges. R-410A refrigerant is close to being an
azeotropic blend (it behaves like a pure compound or
single component refrigerant). The remaining
refrigerant charge, in the system, may be used after
leaks have occurred and then “top-off” the charge by
utilizing the pressure charts on the inner control panel
cover as a guideline.

REMEMBER: When adding R-410A refrigerant, it
must come out of the charging cylinder/tank as a liquid
to avoid any fractionation, and to insure optimal system
performance. Refer to instructions for the cylinder that
is being utilized for proper method of liquid extraction.

WARNING

Failure to conform to these practices
could lead to damage, injury or death.

SAFETY PRACTICES:

1. Never mix R-410A with other refrigerants.

2. Use gloves and safety glasses, Polyol Ester oils can
be irritating to the skin, and liquid refrigerant will
freeze the skin.

3. Never use air and R-410A to leak check; the
mixture may become flammable.

4. Do not inhale R-410A – the vapor attacks the
nervous system, creating dizziness, loss of
coordination and slurred speech. Cardiac
irregularities, unconsciousness and ultimate death
can result from breathing this concentration.

5. Do not burn R-410A. This decomposition
produces hazardous vapors. Evacuate the area if
exposed.

6. Use only cylinders rated DOT4BA/4BW 400.

7. Never fill cylinders over 80% of total capacity.

8. Store cylinders in a cool area, out of direct
sunlight.

9. Never heat cylinders above 125°F.

10. Never trap liquid R-410A in manifold sets, gauge
lines or cylinders. R-410A expands significantly
at warmer temperatures. Once a cylinder or line is
full of liquid, any further rise in temperature will
cause it to burst.

START UP (Continued)

IMPORTANT INSTALLER NOTE

For improved start up performance wash the indoor coil
with a dish washing detergent.

HIGH PRESSURE SWITCH

All W**A/W**L wall mounted air conditioner series
models are supplied with a remote reset for the high and
low pressure switch. If tripped, this pressure switch may
be reset by turning the thermostat off then back on again.

THREE PHASE SCROLL COMPRESSOR
START UP INFORMATION

Scroll compressors, like several other types of
compressors, will only compress in one rotational
direction. Direction of rotation is not an issue with
single phase compressors since they will always start
and run in the proper direction.

However, three phase compressors will rotate in either
direction depending upon phasing of the power. Since
there is a 50-50 chance of connecting power in such a
way as to cause rotation in the reverse direction,
verification of proper rotation must be made.
Verification of proper rotation direction is made by
observing that suction pressure drops and discharge
pressure rises when the compressor is energized.
Reverse rotation also results in an elevated sound level
over that with correct rotation, as well as substantially
reduced current draw compared to tabulated values.

Verification of proper rotation must be made at the
time the equipment is put into service. If improper
rotation is corrected at this time, there will be no
negative impact on the durability of the compressor.
However, reverse operation for over one hour may have
a negative impact on the bearing due to oil pump out.

NOTE: If compressor is allowed to run in reverse rotation

for several minutes, the compressor’s internal
protector will trip.

PHASE MONITOR

All units with three phase scroll compressors are
equipped with a 3 phase line monitor to prevent
compressor damage due to phase reversal.

The phase monitor in this unit is equipped with two
LEDs. If the Y signal is present at the phase monitor
and phases are correct the green LED will light.

If phases are reversed, the red fault LED will be lit and
compressor operation is inhibited.

If a fault condition occurs, reverse two of the supply
leads to the unit. Do not reverse any of the unit factory

wires as damage may occur.

CONDENSER FAN OPERATION

Applies to W42, W48, W60 and W70 models only. The
condenser fan motor on 230/208 volt, one and three
phase, 60 HZ units is a two-speed motor that comes
factory wired on high speed for peak performance. If
ambient conditions permit, it can be reconnected to low
speed (red wire) for lower sound level. See wiring
diagram.

50 HZ models must have fan wired on low speed.
These models are factory wired on low speed.

SERVICE HINTS

1. Caution owner/operator to maintain clean air filters
at all times. Also, not to needlessly close off supply
and return air registers. This reduces airflow
through the system, which shortens equipment
service life as well as increasing operating costs.

2. Check all power fuses or circuit breakers to be sure
they are the correct rating.

3. Periodic cleaning of the outdoor coil to permit full
and unrestricted airflow circulation is essential.

All three phase compressors are wired identically
internally. As a result, once the correct phasing is
determined for a specific system or installation,
connecting properly phased power leads to the same
Fusite terminal should maintain proper rotation
direction.

The direction of rotation of the compressor may be
changed by reversing any two line connections to the
unit.

Manual 2100-508F

SEQUENCE OF OPERATION

COOLING – Circuit R-Y makes at thermostat pulling
in compressor contactor, starting the compressor and
outdoor motor. The G (indoor motor) circuit is
automatically completed on any call for cooling
operation or can be energized by manual fan switch on
subbase for constant air circulation. On a call for
heating, circuit R-W1 make at the thermostat pulling in
heat contact for the strip heat and blower operation. On
a call for second stage heat, R-W2 makes bringing on
second heat contactor, if so equipped.

COMPRESSOR CONTROL MODULE

The compressor control module is standard on all
models covered by this manual. The compressor control
module is an anti-short cycle/lockout timer with high
and low pressure switch monitoring and alarm relay
output.

Adjustable Delay On Make And Break Timer

On initial power up or anytime power is interrupted to
the unit, the delay on make period begins, which will be
2 minutes plus 10% of the delay on break setting. When
the delay on make is complete and the high pressure
switch and low pressure switch is closed, the compressor
contactor is energized. Upon shutdown, the delay on
break timer starts and prevents restart until the delay on
break and delay on make periods have expired.

During routine operation of the unit with no power
interruptions, the compressor will operate on demand
with no delay.

High Pressure Switch and Lockout Sequence

If the high pressure switch opens, the compressor
contactor will de-energize immediately. The lockout
timer will go into a soft lockout and stay in soft lockout
until the high pressure switch closes
break time has expired. If the high pressure switch
opens again in this same operating cycle, the unit will go
into manual lockout condition and the alarm relay circuit
will energize. Recycling the wall thermostat resets the
manual lockout.

Low Pressure Switch, Bypass, and Lockout
Sequence

If the low pressure switch opens for more than 120
seconds, the compressor contactor will de-energize and
go into a soft lockout. Regardless the state of the low
pressure switch, the contactor will reenergize after the
delay on make time delay has expired. If the low
pressure switch remains open, or opens again for longer
than 120 seconds, the unit will go into manual lockout
condition and the alarm relay circuit will energize.
Recycling the wall thermostat resets the manual lockout.

and the delay on

Alarm Relay Output

Alarm terminal is output connection for applications
where alarm relay is employed. This terminal is
powered whenever the compressor is locked out due to
HPC or LPC sequences as described.

NOTE: Both high and low pressure switch controls are

inherently automatic reset devices. The high
pressure switch and low pressure switch cut out
and cut in settings are fixed by specific air
conditioner unit model. The lockout features,
both soft and manual, are a function of the
Compressor Control Module.

ADJUSTMENTS

Adjustable Delay on Make and Delay on Break
Timer

The potentiometer is used to select Delay on Break time
from 30 seconds to 5 minutes. Delay on Make (DOM)
timing on power-up and after power interruptions is
equal to 2 minutes plus 10% of Delay on Break (DOB)
setting:

0.5 minute (30 seconds) DOB = 123 second DOM

1.0 minute (60 seconds) DOB = 126 second DOM

2.0 minute (120 seconds) DOB = 132 second DOM

3.0 minute (180 seconds) DOB = 138 second DOM

4.0 minute (240 seconds) DOB = 144 second DOM

5.0 minute (300 seconds) DOB = 150 second DOM

During routine operation of the unit with no power
interruptions the compressor will operate on demand
with no delay.

Typical Settings for Dual Unit Installation:

Unit 1: DOB set at 2 minutes, and DOM is 132 seconds
Unit 2: DOB set at 4 minutes, and DOM is 144 seconds

PRESSURE SERVICE PORTS

High and low pressure service ports are installed on all
units so that the system operating pressures can be
observed. A pressure table can be found later in the
manual covering all models. It is imperative to match
the correct pressure table to the unit by model number.
See Table 2.

1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2 Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.
3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article

310 for power conductor sizing.
Caution: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310

regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.
* Top outlet supply option is available only factory installed and only on the selected models.
